82240 Details - New 'old?' - TomC - 11-05-2018 12:03 AM Perhaps this has been documented before: (perhaps in an older doc I could not find.) 1. When the 82240A is in 'Self Test' mode (i.e after receiving <27 254>) - continuously running the character set printout, pressing the LF key on the printer pauses this process. 2. The 'Character Cell' is 5 pixels wide by 7 pixels tall. There are two pixels after each character for spacing - except the 24th character. Thus 24 x (5 +2) - 2 = 166 pixels wide. There is one row of pixels below eash character line. This 8th row below is used for inter-line spacing and character descenders (lower case y and others). When this row is used, it is immediately adjacent to the top row of pixels in the next line. TomC ps: It can't hurt to be reminded - when using the 82240A in graphics mode to remove OLDPRT mapping. |
